Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rotational drive device for a small frame of a reeling machine.

[Prior Art] As is well known, one set of silk reeling machines for reeling raw silk from cocoons is composed of many units, for example, about 400 threads, two sets are arranged back to back, and a cocoon feeder is installed around the large number of silk reeling machines. Once moved, the necessary cocoons are supplied to each reeling machine. The small frames for winding the reeled raw silk are lined up in a row on one side, and a single common drive shaft is used.
Normally, the drive shafts of these small frames are connected in sequence, with 20 pots as one unit. Therefore, the number of rotations of all the small frames in one set is the same.

In response to the recent demand for diversification of raw silk, reeled yarn of various thicknesses has come to be produced. For example, normal raw silk is around 30 denier, but 150 denier
There is also a need for yarns of denier or higher, and there is also a demand for yarns mixed with relatively thick synthetic fiber yarns. As the thread wound around the small frame becomes thicker, (a) it becomes more difficult to dry, and (b) the ability to supply cocoons becomes insufficient. Therefore, the rotation speed of the small frame is lowered to effectively reduce the number of times the thread is attached per unit time. must be exactly the same.

However, according to the prior art, since the number of revolutions of all the small frames in one set is the same, the thickness of the yarn reeled in one set is limited within a certain range. For this reason, even if you try to produce partially thick or thin yarn, for example, 400 threads, the thread thickness of all the reeling machines in one set is constant, so relatively specific threads can be produced in small quantities. If desired, the entire set must be operated for a short period of time, or only some units must be used to reel, leaving other units idle. Such a situation is extremely inconvenient in terms of work efficiency.

[Object of the invention] Accordingly, an object of the present invention is to provide a rotation drive device for a small frame that can vary the number of revolutions of the small frame in one set of reeling machine.

[Configuration of the invention] According to the small frame rotation drive device of the present invention, a first small frame winding shaft that rotationally drives a number of winding small frames for winding yarn in series, and a first small frame are provided. A second small frame winding shaft arranged parallel to the winding shaft, a first drive shaft that drives the small frame winding shaft, and a second drive shaft that can rotate at a speed different from that of the first drive shaft. and includes a transmission mechanism that selectively connects the first and second drive shafts and the first and second small frame winding shafts.

[Operation and effect of the invention] As described above, the present invention is a device for driving winding shafts of small frames arranged in multiple rows, in which two drive shafts whose speeds are changed by a transmission are transmitted between the two drive shafts and the small frame winding shaft. Since the mechanism is configured to selectively connect the yarn, the winding speed of the small frame can be changed for each small frame box according to the thickness of the yarn to be wound. The optimum winding speed corresponding to the denier can be obtained. Therefore, when producing a small amount of yarn of a specific denier, other units are not left idle.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory diagram of an automatic reeling machine to which the present invention is applied, and the cocoon replenishment and cocoon feeding machine 1 shown on the right side of FIG.
The raw silk a collected from the cocoons 2 supplied from
The kennel 6 driven by
It is wound up on a small winding frame 10 on the hook side.

Similarly, on the A pot side shown on the left side of FIG.
Then, it is wound up by the winding small frame 20 on the A pot side. That is, the small winding frame 10 on the B hook side is supported by the small frame winding shaft 13, and this small frame winding shaft 13 is connected to the B main shaft 11 via the small frame box 12.
The motor is driven by a chain 14, an intermediate chain wheel 15, and the like.

Similarly, the small winding frame 20 on the A pot side is also supported by a small frame winding shaft 23, and this small frame winding shaft 23 is powered by the small frame box 22, which is driven from the A main shaft 21 via a chain 24. It rotates by. Therefore, by changing the rotational speed of the A spindle 21 and the B spindle 11, the winding speed of the winding frame on the A hook side and the winding frame on the B hook side can be changed.

The drive mechanism for the small frame winding shaft is as shown in FIG.
6 is transmitted to the A main shaft 21 via the chain 27.

The rotation of the A main shaft 21 is transmitted to the small frame box 22 via the chain 24, and a removable bearing fitting 30 drives the small frame winding shaft 23 on the A hook side.

As shown in FIG.
and are connected sequentially. This connection fitting 4
0 is a type of shaft coupling, in which a fitting having a concave portion 41 is attached to one shaft 23a, and a fitting having a convex portion 42 is attached to the other shaft 23b, thereby making it possible to transmit the rotational force of the shaft. be. That is, if the connecting fitting 40 is connected, the left shaft 23a and the right shaft 23b rotate as one. By selectively connecting the bearing fittings attached to the shaft ends of the left and right shafts connected by this connecting fitting to either one of the small frame boxes, different rotational speeds can be applied to the winding shaft. can.

Specifically, the left shaft 23a is driven by the small frame box 22a, and the right shaft 23b is driven by another small frame box 22b via the bearing fitting 30b. The small frame box 22b side is given a different rotation speed from that of the small frame box 22a. As shown on the right side of FIG. 2, as a rotational speed change mechanism, for example, a spur gear 35 is attached to the end of the A main shaft 21, and a gear 36 that meshes with this gear drives a transmission 37, and its output is By transmitting it to the B main shaft 11,
The rotational speed of the A main shaft 21 and the B main shaft 11 can be changed. By transmitting this changed rotational speed to the small frame box 22b through the gear mechanism 38, the desired purpose can be achieved.

The above explanation is based on the case where the rotation speed of the B main spindle is given using the connection fitting of the winding shaft in the leftmost block of the small frame winding shaft 23 on the A pot side in FIG. 2. However, this can be achieved by using a transmission mechanism consisting of a gear 50 in which the winding shafts 13a and 13b on the B hook side on the right end side in FIG. It is also possible to drive only the small frame of the part by the A main shaft. Incidentally, the left and right shafts may be connected to shaft joints in portions where the small frame winding shaft does not need to be rotated by a joint 45 that allows the left and right shafts to rotate arbitrarily. In addition, the A spindle 21 and the B spindle 11
They may be rotated by separate motors without being connected by gears. In that case, the rotation speed of the motor itself may be changed, or a transmission may be used.

In addition to the transmission mechanism explained above, the present invention also includes:
A transmission mechanism is provided that selectively connects the A main shaft and the B main shaft to the small frame winding shaft to drive the small frame winding shaft at variable speeds for each unit. FIG. 4 is a reproduction of the speed change state shown in FIG. 1, in which the A main shaft 21 and the small frame box 22 are driven by changing the speed of the output of the driving motor 25 shown in FIG. 2 by a transmission 26. are connected by a chain 24 to drive the small frame winding shaft 23.

As a result, the winding small frame 20 in the A side block
Winding is performed at the rotational speed given by the small frame winding shaft 23. On the other hand, the B spindle 11 is
is driven at a different rotation speed. As described above, the transmission 37 of the B main shaft 11 drives the B main shaft 11 by changing the input rotational speed given from the gear mechanisms 35 and 36 provided at the ends of the A main shaft 21. and,
Since the small frame box 12 and small frame winding shaft 13 of the B side block are driven by the B main shaft 11 whose speed has been changed, the winding small frame 10 of the B side block is driven by the A
Winding can be performed at a different rotational speed from that of the winding frame 20 of the side block.

Next, in the transmission mechanism shown in FIG. 5, the B main shaft 11 drives the B side block, and the A side small frame winding shaft 23 is driven via the chain 28, intermediate gears 29a, 29b, etc. This is what I did.

In this state, all the small frames of the A side block and the B side block are driven by the B main shaft. moreover,
In other shifting states shown in FIG. 6, the A main shaft 2
1 shows the case where the B side block is also driven. In this case, the gear 5 provided on the A main shaft 21
The transmission path is configured to drive the small frame gearbox 12 through the intermediate spur gear 16 that meshes with the gearbox 16.
In the case of this speed change, both the A side block and the B side block are driven by the A main shaft 21.

When a specific unit, for example, the unit U1 in FIG. 2, is rotated slowly, normally the small frame winding shafts 23a and 23b are integrally connected by a connecting fitting 40, as shown in FIG. 7A. The shaft 23b is detachably attached to a small box 22b rotated by a gear G.

Therefore, the shafts 23a and 23b are removed, and other shafts 23x and 23y, which do not have the connecting fittings 40 and are not connected to each other as shown by the reference numeral 40a, are installed as shown in FIG. 7B. In this way, the shaft 23x and the shaft 23y can be rotated separately,
Only unit U1 can be rotated at a slow speed.

If two types of small frame rotating shafts are prepared in advance in this way, specific ones of the A block and B block can be rotated at different speeds.

[Summary] As described above, the present invention is based on the A
This is a device that rotates between the drive shafts of the main shaft and B main shaft, and a small frame winding shaft divided into two blocks, A and B. (1) The A main shaft drives both the A block and the B block.

(2) Both A block and B block are driven by the B spindle.

(3) The A spindle drives the A block, and the B spindle drives the B block.

(4) It is possible to obtain four speed change states in which only a specific unit is driven at a different speed from the others.

In this way, by using a mechanism that connects only a specific section of the small frame winding shafts of the A and B blocks to the mating drive shaft, it is possible to obtain different combinations of rotational speeds for each unit. Therefore, yarns with different deniers are
The yarn can be reeled properly with two sets.
